Step-by-step explanation:
The probability that Allen will select a red marble and the coin will land heads up is 1/10.
To find the probability that Allen will select a red marble and the coin will land heads up, we need to consider two independent events: selecting a red marble and tossing a fair coin.
The probability of selecting a red marble is the number of red marbles (4) divided by the total number of marbles in the box (4 + 8 + 3 + 5 = 20):
Probability of selecting a red marble = 4/20 = 1/5.
The probability of the coin landing heads up is 1/2 since it's a fair coin.
Now, to find the probability of both events occurring together (selecting a red marble and getting heads up), we multiply the probabilities of each event:
Probability of selecting a red marble and getting heads up = (1/5) * (1/2) = 1/10.
So, the probability that Allen will select a red marble and the coin will land heads up is 1/10.

what is the input value other than 7 for which g(x)=4
Given:
It is given that the value of the graph when the input 7 is [tex]g(x)=4[/tex]
We need to determine the value of x when [tex]g(x)=4[/tex]
Value of x when [tex]g(x)=4[/tex]:
The value of x can be determined by using the graph.
From the graph, we need to determine the value of x when [tex]g(x)=4[/tex] other than the value x = 7.
This can be determined by finding the point at which the line meets the point y = 4, we can find the corresponding x - value.
Thus, from the graph, it is obvious that the graph also meets the point y = 4 when x = -8.
Therefore, the input value is x = -8 which makes [tex]g(x)=4[/tex]
Hence, the input value other than 7 for which [tex]g(x)=4[/tex] is x = -8.
The input value other than 7 for which g(x) = 4 is x = -8.
It is given that the value of the graph when the input 7 is g(x)=4
We need to determine the value of x when g(x)=4
Value of x when g(x)=4:
The value of x can be determined by using the graph.
This can be determined by finding the point at which the line meets the point y = 4, we can find the corresponding x - value.
From the graph, we get that the graph of g(x) passes through the point (x = -8, y = 4),
Thus, from the graph, it is obvious that the graph also meets the point y = 4 when x = -8.
Then indeed, the input value (x) other than 7 for which g(x) = 4 is x = -8.
As, the function g(x) takes the value of 4 at x = -8, according to the graph.
Therefore, the input value is x = -8 which makes g(x) = 4.
Hence, the input value other than 7 for which g(x) = 4 is x = -8.

write the number in scientific notation
Answer:
in scientific notation the answer is 5.75x10^8
Answer: [tex]5.75[/tex] [tex]x[/tex] [tex]10^{8}[/tex]
Step-by-step explanation: To write a number in scientific notation, first write a decimal point in the number so that there is only one digit to the left of the decimal point.
So here, we have 5.75000000 and notice that there
is only one digit to the left of the decimal point.
Next, we count the number of places the decimal point would
need to move to get back to the original number, 575,000,000.
Since we would need to move the decimal point 8 places to the right,
we have an exponent of positive 8.
Now, scientific notation is always expressed as a number between 1 and 10 including 1 but not 10 and it is multiplied by 10 to a certain power that must be an integer.
So we have [tex]5.75000000[/tex] [tex]x[/tex] [tex]10^{8}[/tex].
Notice that the exponent is positive.
This is because we would need to move the decimal point to the right in order to get back to the original number.
So 575,000,000 can be written in scientific notation
as [tex]5.75000000[/tex] [tex]x[/tex] [tex]10^{8}[/tex] or just [tex]5.75[/tex] [tex]x[/tex] [tex]10^{8}[/tex].
Remember that we can drop zeroes at the end of a decimal.
So we have [tex]5.75[/tex] [tex]x[/tex] [tex]10^{8}[/tex].
If each necklace chain is 18 inches long, how many necklaces can be made from 137.16 centimeters of silver chain?
Answer:
3
Step-by-step explanation:
to convert the centimeters to inches, divide 137. 16 by 2.54
you should get 54
then divide by 18
you get three
You can make 3 necklaces from 137.16 centimeters of silver chain, given that each necklace is 18 inches long. We first converted the necklace length to centimeters, and then divided the total length of silver chain by the length of each necklace.
Explanation:To find out how many necklaces can be made from 137.16 centimeters of silver chain, we first need to convert the units because the length of the necklace chain is given in inches, while the total amount of silver chain is given in centimeters.
We know that 1 inch is equal to 2.54 centimeters. Therefore, if each necklace is 18 inches long, the length of each necklace in centimeters is 18 inches * 2.54 cm/inch = 45.72 cm.
Now, to find the number of necklaces that can be made, we divide the total length of silver chain by the length of each necklace. That is 137.16 cm / 45.72 cm/necklace = 3 necklaces (rounded down to the nearest whole necklace, because we cannot make a fraction of a necklace).

M varies inversely as the square of P. If M is 9 when P is 2, then find M when P is 3.
please h e l p
Answer:
Step-by-step explanation:
If two quantities are inversely proportional, it means that an increase in the value of one variable would cause a corresponding decrease in the other variable and vice versa.
Given that M varies inversely as the square of P, if we introduce a constant of proportionality, k, the expression becomes
M = k/P²
If M = 9 when P = 2, then
9 = k/2² = k/4
k = 9 × 4 = 36
Therefore, the inverse variation equation is
M = 36/P²
When P = 3,
M = 36/3² = 36/9
M = 4
Prove that the following is a right – isosceles triangle.
Show work
Answer:
Proved down
Step-by-step explanation:
To prove that a triangle is isosceles use the distance formula to find the length of its side and check if there are two sides equal.
To prove that a triangle is right find the square of the longest side and then find the sum of the squares of the other two sides, if the two answers are equal, then the triangle is right (converse of Pythagoras Theorem).
The formula of the distance between two points is:
[tex]d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]
∵ x = (-1 , 5) and y = (4 , 4)
∴ [tex]x_{1}[/tex] = -1 and [tex]x_{2}[/tex] = 4
∴ [tex]y_{1}[/tex] = 5 and [tex]y_{2}[/tex] = 4
- Substitute them in the formula of the distance to find xy
∵ [tex]xy=\sqrt{(4--1)^{2}+(4-5)^{2}}=\sqrt{25+1}[/tex]
∴ [tex]xy=\sqrt{26}[/tex]
∵ x = (-1 , 5) and z = (-2 , 0)
∴ [tex]x_{1}[/tex] = -1 and [tex]x_{2}[/tex] = -2
∴ [tex]y_{1}[/tex] = 5 and [tex]y_{2}[/tex] = 0
- Substitute them in the formula of the distance to find xz
∵ [tex]xz=\sqrt{(-2--1)^{2}+(0-5)^{2}}=\sqrt{1+25}[/tex]
∴ [tex]xz=\sqrt{26}[/tex]
∵ xy = xz
- The isosceles triangle has two equal sides
∴ Δ xyz is an isosceles triangle
∵ y = (4 , 4) and z = (-2 , 0)
∴ [tex]x_{1}[/tex] = 4 and [tex]x_{2}[/tex] = -2
∴ [tex]y_{1}[/tex] = 4 and [tex]y_{2}[/tex] = 0
- Substitute them in the formula of the distance to find yz
∵ [tex]yz=\sqrt{(-2-4)^{2}+(0-4)^{2}}=\sqrt{36+16}[/tex]
∴ [tex]yz=\sqrt{52}[/tex]
yz is the longest side lets find its square
∵ (yz)² = ([tex]\sqrt{52}[/tex] )²
∴ (yz)² = 52
- Lets find the sum of the squares of the other two sides
∵ (xy)² + (xz)² = ([tex]\sqrt{26}[/tex] )² + ([tex]\sqrt{26}[/tex] )²
∴ (xy)² + (xz)² = 26 + 26 = 52
∴ (yz)² = (xy)² + (xz)²
- That means the angle opposite to yz is a right angle
∴ Δ xyz is a right isosceles triangle

1 occurs 1 time3 occurs 2 times4 occurs 1 time5 occurs 1 time6 occurs 1 time8 occurs 1 time9 occurs 1 time10 occurs 1 timeSince the number 3 appears more frequently than any other number in the set, occurring twice, the mode of this set of numbers is 3.
The amount of money nick spent on 12 cans of soda was $3. Write an equation relating the amount spent to the the number of cans purchased. Then find out how many cans you can buy for $28.50.
Answer:
12y=$3
114 cans
Step-by-step explanation:
Let the cost of every can be represented by y. Therefore, for 12 cans, the cost will be the product of y cans and 12 hence cost is 12y
Since the cost incurred is $3 then we can represent these as
12y=$3
To solve for y, we divide both sides by 12 hence
Y=$3/12=$0.25
To find the number of cans that one will get with a buget of $28.5, we divide the budget by the cost of a can. This will be $28.5/$0.25=114 cans
